The present invention is directed to improvements in wind motors.

The primary object of the invention is to provide a device of thischaracter so construct that the vanes will be positively held in suchposition that their surfaces will be presented to the wind, said vanesbeing releasable when desired, either automatically or manually.

Another object ot the invention is to provide a device of this characterso constructed that should the wind reach above a certain velocity thevanes will be released so that their edges will be presented to the windin order to prevent injury to the motor.

inthe accompanying drawing:

Figure 1 is a top plan view ot the device.

Figure 2 is a sectional View on line 2 2 ot Figure 1. Y

Figure 3 is a sectional view on line 3 3 of Figure 1.

The wind motor comprises upper and lower hubs 1 and 2 maintained inspaced relation by brace members 3 ot any suitable const-ruction, saidhubs being fixed upon the drive shaft 4. These hubs have radiating there`trom spokes 5 and 6, also braced by the member 3. The spokes areconnected by vertical standards 7 having guides 8 carried thereby, thepurpose of which will be later explained.

The propelling vanes are provided with shafts 10 which are iiXed theretooli center and have their ends 'journaled in the bearings 11 and 12carried by the respective spokes 5 and 6. The shaft 4 has its lower endjournaled in a supporting traine 13 and has fixed thereto a. gear 14 ofany suitable type forv tfansniitting power. Slidably seated. upon theshaft 4 is a plate 15 carrying brackets 16, there being an expansionspring 17 encircling the shalt and interposed between the gear 14 andplate.

Associated with each vane 9 is a lever 17 pivotally connected, as at 10to the assoelated spoke 5, said levers having weights 18 upon theirupper ends, coil springs 19 connecting the levers 17 with the upperend`V U to blow. li drum 34 is fixed to the lower end y of the shaft r4and has engaged thereon a fbralrerband 35 operable to prevent rotationIof the shaft 4. Latch bars 20 are pivotally connected to the levers 17and are slidable in the guides 8, said levers having one of the 1927.Serial N0. 209,055.

ends of the cables 21 secured to their lower ends which are trained overpulleys 22 supported by the brace member 3. The other `ends of thecables are secured to the brackets 1G. l

A yoke 23 is provided and has its arms 24 slidable in the traine 13,said arms having rollers 25 upon their upper ends 'for ing the uppersurface ot the plate 15. El hand lever 26 is pivotally connected at oneend to C presented to the wind. It will be of course understood that thelatch bars 20 are employed :tor maintaining certain of the vani-s `withtheir sides presented to the wind. The spolres 5 are connected by therim 28 and spokes 6 are connected by rim 29, and mounted upon the lowerrim adjacent each v is a latch 30 which includes a spring pres...-yinclined pivotally mounted plate 31, said plate serving to engage thevaries in case o'l reverse swinging thereof but permitting the same toride thereover.

Mounted upon certain of the upper spokes 5 are supplemental" aines 32which pivotally support the auxiliary vanes 33, said trames havingstops31 carried thereby to limit the winging movement oit the auxiliaryvanos. rl`hese vanes serve to start the device when the saine stops inarcaln., since they will be in a position to oder resistance to the windand rotatethe device until. the vf" es il are positioned tor action bythe wind; ren the varies 9 have been released by the automatic operationoi' the latch bar 2O and have their edges presented to the wind, and acalm ocA curs, the auXiliaryva-nes 33 will then operate to startthedevice when the wind again starts tit) of the device in order that thevanes 33 which are comparatively small will not act to start the devicebefore it is desir-ed to do so.

Then it is desired to stop the motor the lever 26 is forced downwardly,thus carrying the yoke downwardly so that the rollers carried therebywill move the plate l downs wardly, thus drawing npon the cables toswing the levers to permit the withdrawal of the latch bars 2() fromengagement with the Lvseees vanes pivotally mounted between the spokes,levers pivotally supported by certain of the spokes, latch barspivotally connected to the levers and engageable with the vanes toarrest the pivotal movement thereof in one direction, flexibleconnections between the plate and levers, and means for operating theyoke to shift the levers to actuate the latch bars to permit freeswinging of the vanes.

vanes S), thus permittingT the vanes to present VALTER S. SCHLOTZHAUER.their edges to the wind. Any suitable means may be provided for holdingthe lever in its down position.

Having thus described the invention. I claim l 1. A wind motorincluding` a drive shaft, hubs carried by the shaft, spokes carried bythe hubs, standards connecting the spokes and having guides carriedthereby, vanes pivotally connected between the spokes, latch warsslidable in the guides for engaging the Yanes to arrest the swingingmovement thereof, levers ivotally connected to certain ofthe spokes anwith the latch bars, yieldable connections between the shaft and levers,said levers being operable by centrifugal force to withdraw the latchesto permit free swinging of the vanes, and independ-ent means forswinging the levers for disengaging the latches from the vanes.

2. A Wind motor comprising a drive shaft, hubs carried by the shaft,spokes carried by the hubs, standards connecting the spokes, 3;. vanespivotally mounted between the spokes, Y

levers pivotally connected with certain of the spokes, latch arspivotally connected with the levers and slidably supported by thestandards, and adapted to engage the vanes i to hold them in Windresisting positions, a plate yieldably seated upon the shaft, flexibleconnections between the plates and levers, and manually controlled meansfor lowering the plate to actuate the flexible connections to rock thelevers, thereby sliding the latch bars from engagement with the vanes.

3. A wind motor including a drive shaft vertically spaced hubs carriedby the shaft, s okes carried by the hubs, frames carried by t 1euppermost spokes and having stops, vanes pivotally mounted between thespokes, latch harsslidably associated with the vanes for limitin theswinging movement thereof, means for disengaging the latches from the ivanes, and auxiliary' vanes pivotally mounted in the frames and adaptedto engage the stops to hold said auxiliary vanes in wind resistingposition.

4. A Wind motor including a frame, a shaft having its lower endjournaled in ythe frame,

a plate slidably and yieldably supported on the shaft, a yoke slidablyassociated with the frame and having rollers carried thereby for englement with the plate, hubs carried' by G* the s aft and having spokescarried thereby,
